Tocl'l when it mm concern:

Be it known tiiat I Lows Pnimr Dasnames, a citizen of the United states, and a resident of Ware, iii the county of Hampshire and State of Massachusetts, have made certain new and useful 1m rovements in Tire-Linings, of which the to owing is a specification, v p

My invention i'elates to tire hnin' s es e ciall those linin s which areplaced etween the Inner tube a H outer casin of a pneumatic tire, and it consists te combinations, constructions, and mangemerits herein described and claimed.

An object of n invention is to provide a knitted fabric or covering inner tifies, said fatn'c being-continuing in new e being so shaped as to ohviate the formation of wrinkles or dresses. g

A farther ob'e'ct of m invention i to provide a lining o the t e described in which the circular fornr e the tire is s proximated by the woven article so the: when placed in position vef slight sttetehingg will bring the lining ihtd such a position as to preclude the possibility oi creases or Wrinkles; I

A further objectof my invention is'to provide a device of the type described which may also be men as" intermediate layers in the construction of outer casings for pneuniatic ti'i'es. p r

Other objects and advantages will appear in the following specification and the novel features of the device will be particulari pointed out in the appended claims.

My invention is illustrated in the accompanying drawings forming part of this application in which Figure 1 is a face View of a lining constructed according to my invention, Fig. 2 is a plan view of a portion of the inner side of the lining, Fig. 3 is a perspective view showing the lining applied to an inner tuloe Fig. 4 is :1 transverse section through the lining and inner tube, Fig. 5 is a section through an outer casing showing the manner in which the fabric is disposed, and Fig. 6 is a section through a modified form of the device.

It is cliiiicnlt to make contiiiuous woven linings for tires due to the fattthat wrinkles are a o t to form when the fabric is bent into circu ar form. Therefore it is necessary to cut woven fabric into strips, the ends of these strips overlapping.

In carrying out my invention i make use, as stated aheve, of a knitted fabric which is particularly wel'i' adapted for linings in that a knitted fabric can bent witho'i'it creativ where a wdveii fabric cannot, be-

cause 0 the first that the peculiar construe taken out. The machine makes a cylindrical 7 person I having a dro ped stitch along the line 2 (see 2). his is to serve as a guidefor slitting the fabric to insm't the inner tube of the tire. I

Rt semispasse-shame intervals a 3' is provided. In making this gusset e11 oft-he needles hilt about one-eighth at the front of the machine are thrown out of operation. Their byre'ciproeatory kzri'tting the needies' on each side of the gap or space are grad-nah? thrown into action with there remain only about one-eighth out of operation at the Beck of the .nraichine, again by feciprocatory knitting the same needles are gradually thrown out of operation until about one-eighth remain in action at front of machine. Then ail the needles are put into operation at one time. This operation produces a tapered gusset which increasesv the length of the fabric on one side. Now when the needles are all brought into operation another cylindrical length 1 is made, then the gusset 3 is made and the operation is repeated alternately. 1 It will be understood that this lining is knitted in long lengths which are out Into pieces suitable for the inner linings of tubes of the size desired, that is to say, or a tire to fit a wheel thirty inches in diameter the tube length would be substantially equal to the circumference of the wheel; for a thirty-two inch wheel the length would. of crnirse be increased since the circumference of the thirty-two inch wheel would be increased. These lengths are then out along the guide line 2 and the ends of each length are looped together, thus forming a structure similar to that shown in Fig. 1. The inner tube of the tire is now placed inside of the lining, as shown in Fig, 4, and then the lining with the inner tube are placed in the inner casing or shoe of the tire.

In Fig. 1 I have shown the gussets by means of dotted lines, but it will be understood that there is really no break or interruption in the fabric at these points, the stitches being continuous. Thus in Fig. 3 which shows the fabric extended there is a continuous lining which has no creases or folds.

The lining made in the manner described is also well adapted for linings of straight tubes such as rubber hose, since, as stated, it can be straightened out without producing wrinkles. Such a construction is shown in Fig.6 in Which 7 denotes layers of fabric and 8 layers of rubber.

In Fig, 5 I have shown another n1odification in which the outer casing which is constructed largely of layers of rubber .l is provided with layers of fabric 10.

It wi l be seen that I have provided a lining of fabric which will readily adapt itself to be bent into a circular form or to be straightened out. In either case the fact that it is knitted and the further fact that the gussets are provided tend to make a lining Which may be used for both purposes.

I claim:

l. A lining for rubber tubes comprising a knitted fabric, consisting'of a plurality of cylin'rical sections having their axes inclined and provided with an integral gusset at the ends of adjacent sections.

A. lining for rubber tubes comprising a knitted fabric consisting of a pluralitv nr' cylindrical sections having their axes inclinco and provided with an integral gusset at the ends of adjacent sections, said gusset being of substantially a wedge shapeand being a continuation of the stitches of the cylindrical portions on either side thereof.

3. In a lining for pneumatic tires, a substantially circular continuous tube comprising a series of cylindrical sections, adjacent sections having their axes inclined toward one another and their inner edges abutting one another, and gussets disposed at the ends of adjacent sections.

1. In a lining for pneumatic tires, a substantially circular continuous tube comprising a series of cylindrical sections, adjacent sections having their aXcs inclined toward one another and their inner edges abutting one another, and edge-shaped gusscts disposed at the ends ol adjacent sections, said gussets forming integral continuations of the cylindrical portions on each side thereof.

5. In a lining for pneumatic tires, a substantially circular continuous tube comprising a series of cylindrical sections, adjacent sections having llieiraxcs inclined tou ard one another and their inner edges abutting one another, and \vedgcshaped gussets disposed at the ends of adjacent sections, said 'gusscts forming integral continuations of the cylindrical portions on each side thereof, the inner sides of said cylindrical portions being provided with a guide for cutting the
